GLOSSARY
Access Point
A device that provides transparent access between Ethernet wired networks and
IEEE 802.11 interoperable radio-equipped mobile units. Hand-held mobile
computers, PDAs or other devices equipped with radio cards, communicate with
wired networks using Access Points (AP). The mobile unit (mobile computer) may
roam among the APs in the same subnet while maintaining a continuous, seamless
connection to the wired network.
Barcode
A pattern of variable-width bars and spaces which represents numeric or
alphanumeric data in binary form. The general format of a barcode symbol consists
of a leading margin, start character, data or message character, check character (if
any), stop character, and trailing margin. Within this framework, each recognizable
symbology uses its own unique format.
Baud Rate
A measure for data transmission speed.
Bit
Binary digit. One bit is the basic unit of binary information. Generally, eight
consecutive bits compose one byte of data. The pattern of 0 and 1 values within the
byte determines its meaning.
Bluetooth®
A standard radio technology using a proprietary protocol. The onboard Bluetooth®
module in the mobile computer is compatible with the 1.1 protocol.
Byte
On an addressable boundary, eight adjacent binary digits (0 and 1) combined in a
pattern to represent a specific character or numeric value. Bits are numbered from
the right, 0 through 7, with bit 0 the low-order bit. One byte in memory can be used to
store one ASCII character.
Decode
To recognize a bar code symbology (e.g., Codabar, Code 128, Code 3 of 9,
UPC/EAN, etc.) and analyze the content of the bar code scanned.
